The NORVI X-DA8 is an expansion module with eight 230 V AC digital inputs for the modular NORVI X controller platform.

Each input is opto-coupler isolated from the CPU side. The integrated PCA9538 I²C port expander transfers input states to the NORVI X CPU module through the internal expansion bus. Four I²C addresses can be selected using DIP switches, allowing up to four X-DA8 modules to be operated on one controller.
